Title: Healthcare software services open interfaces and standards in Finland


1
Healthcare software services- open interfaces
and standards in Finland
  • HL7/OMG Healthcare Services Specification Project
  • London, 31 Jan 2006
  • Juha Mykkänen, University of Kuopio, HIS RD unit
  • SerAPI project, HL7 Finland CS SIG

2
Overview
  • healthcare health information systems in
    Finland
  • open service-oriented interfaces efforts and
    specifications in Finland
  • HL7 Finland Common Services SIG
  • PlugIT project
  • SerAPI project
  • comparison of three services
  • experiences
  • national efforts
  • HSSP

Healthcare HIS in Finland
  • Healthcare in Finland
  • Population 5.3 million
  • Life expectancy 74.6 / 81.5 years
  • GDP per capita 28,646 EUR (2004)
  • Growth competitiveness index score (World
    Economic Forum 2005) 5,94 (1st)
  • Healthcare 7.6 of GDP
  • Public healthcare funded by taxation
  • Basis 278 primary health centres by 444
    municipalities
  • 5 university 32 central/district hospitals in
    20 districts associations of municipalities
  • Private care 14
  • Occupational health by private organisations
  • Information systems in healthcare in Finland
  • In primary health care, EPR used by 98 of GPs
  • In hospitals, HIS used since 1980s
  • Now EPR to hospitals, integration, migration,
    web-based systems National interoperable EHR by
    2007?

Background HL7 Finland Common Services SIG
  • HL7 Finland
  • held its 10th anniversary in October 2005
  • HL7 v2.3 messaging widely used in some domains
  • active in national work for EHR
  • CDA r2 used as a basis for the structure and
    archiving
  • HL7 Finland Common Services SIG (2002-)
  • initial focus on clinical context integration
    (CCOW)
  • work on service specifications from the
    background projects - national comments,
    balloting
  • 3 available specification areas implementation
    guides

5
Background PlugIT project
www.plugit.fi
Natl. healthcare programme / National EHR project
3 univ. depts, 1 polytechnic
12 applications vendors, 3 technology vendors
6 hospital districts, 2 municipalities
  • National RD project to develop integration
    solutions for healthcare
  • Results Service specifications, integration
    methods, centre of expertise
  • Oct 2001Aug 2004, about 15 full-time 15
    part-time researcher/developers
  • Budget 2 million, 84 by National Technology
    Agency TEKES

6
Background SerAPI
  • SerAPI project (2004-2007)
  • national RD project
  • service-oriented architecture and web services
  • 14 software companies, 4 public healtcare
    organisations, 3 research units
  • process / application / platform viewpoints
  • service specifications, methods and tools
  • participation in standards development (national
    / international)
  • Healthcare Services Specification Project
  • participation through both OMG and HL7
  • infrastructure work / individual services

7
Open service specifications
  • HL7 Finland accepted
  • Context Management (context repository) CCOW
  • Core services User Person information access
    Access control EIS, OMG PIDS
  • Core services CodeAPI Common Terminology
    Services Vocabulary API, OMG TQS
  • other publicly available
  • DRG classification
  • OID generation
  • other in progress and related
  • scheduling e-booking
  • decision support
  • patient lists, care relationship, etc.

8
Service implementations
  • several context service applications
  • context services available in core applications
    in hospitals and health centres
  • low effort implementation for single sign-on
    patient synchronisation
  • recent additions for security in regional
    information systems
  • core service implementations in university
    hospitals
  • implementations in new core hospital systems
  • also legacy applications wrapped with interfaces
    - migration
  • several proprietary services, some specifications
    available in public
  • DRG classification, care relationship, decision
    support service pilot etc.

9
Approach interface technologies
  • incremental specification from functional
    interface specification to technology-specific
    interfaces
  • simple http communication (context management)
  • http XML (user, person, etc. HL7
    specifications)
  • WSDL/SOAP with WS-I, "API style" (versions of
    user, person etc. core services, DRG, OID)
  • in addition to
  • CDA documents (national EHR core technology) -
    national "services"
  • HL7 messaging (v2.3 ? v3 Web services
    transport)
  • others (EDI, custom solutions..)

10
Different types of services three cases
  • DRG (Diagnosis Related Groups) classifier
    interface
  • resource utilisation groups (NordDRG) to support
    e.g. invoicing and benchmarking
  • EPR (Electronic Patient Record) archive
    interfaces
  • variety of clinical documents stored in archives
    on organisational, regional and national level -
    note national solution not yet specified
  • Context repository
  • single sign-on, synchronisation of several
    applications (used by one user) to one patient at
    a time etc.

Comparison of service scenarios 1

Comparison of service scenarios 2

Emphasis in Finnish efforts
  • increased plug and play, reduced local tailoring
  • simplicity and genericity start from minimal but
    sufficient
  • implementability
  • low introduction threshold
  • compatibility with existing systems
  • defined path from requirements to implementations
  • services as one part of the big picture
  • CDA (moving from regional to national level)
  • messaging (v2 ? v3 transition is beginning)
  • emerging architectures on local, regional and
    national levels
  • three-partite collaboration (vendors, hospital
    districts, research)

14
Lessons observations
  • important pragmatic approach and right timing
  • acknowledge different types of services
  • clear usability improvement, low introduction
    threshold and little invasiveness have fostered
    the most uptake
  • start where there is most repeated point-to-point
    integration
  • nail down both functionality and information
    (does not mean sacrificing flexibility)
  • a unifying architecture would help
  • differences in organisations, in regions and
    nationally
  • "where to put the mandate.."
  • HSSP practical, community-driven,
    multi-platform...
  • SOA main benefits flexibility and
    interconnectivity
  • moving from closed consortia to open standards
    community
  • but quite bad conference call times for Europeans
    (EET) .. )
